K'Chain Che'Malle

Pencil drawing of a creature from the Malazan Empire series by Steven Erikson.

There are various "strains" or types of these creatures described in the books, but the K'Chain Che'Malle variant is most prominently featured, and are the soldiers in a hive-like society. Described as giant bipedal reptilians with swords instead of arms. Based on the descriptions I thought of them as resembling a Tyrannosaurus Rex in build and size.
